Is this BS, or a genuine contribution to the munchkin future? I can't 
tell... but my hunch is, no. Anyone else?

>MURRAY HILL, N.J.--(BUSINESS WIRE)--Oct. 9, 2001--Researchers at 
>Bell Labs, the research and development arm of Lucent Technologies 
>(NYSE:LU - news ), have announced a software breakthrough that will 
>enable global roaming across all wireless network types, including 
>third-generation (3G) technologies such as CDMA2000, Universal 
>Mobile Telecommunications Services (UMTS) and other high-speed data 
>access technologies such as 802.11.
>
>The software architecture, called Common Operations (COPS), will 
>allow mobile subscribers to access voice and data services, 
>information, and messages when they are roaming outside of their 
>home network, even in regions where different types of wireless 
>networks predominate. It will also help mobile operators to upgrade 
>and manage their networks more efficiently, improve operational 
>performance, and reduce errors and expenses.
>
>COPS features a unique ``protocol gateway'' capability that 
>translates data from networks employing a variety of protocols into 
>a single, common language. This makes it possible to maintain a 
>single subscriber profile -- including authentication, authorization 
>and location data -- that can be accessed from a variety of network 
>types.
>
>``As next-generation high-speed mobile data networks emerge and new 
>mobile Internet services are introduced, IP and cellular systems 
>must be able to route calls and deliver services to one another 
>efficiently,'' said Paul Mankiewich, chief technology officer of 
>Lucent's Mobility Solutions Group. ``This breakthrough from Bell 
>Labs will, in the near future, help mobile operators to meet the 
>demand for high-bandwidth services from increasingly mobile 
>subscribers.''
>
>Global wireless roaming is not possible today because various 
>wireless network types cannot work together to identify, 
>electronically, the location of mobile subscribers. For example, a 
>subscriber whose mobile operator uses Code Division Multiple Access 
>(CDMA) technology is not currently able to access services when 
>roaming on a Global System for Mobile Communications (GSM) network.
>
>For a subscriber to initiate a mobile call or activate services such 
>as voicemail, the wireless network must be able to identify the 
>subscriber's location, obtain the subscriber's profile (listing the 
>allowed services), validate the caller's right to the services and 
>then authenticate the caller. Home location registers (HLRs), which 
>are databases of subscriber information, currently perform these 
>functions only when wireless subscribers travel in their home 
>networks, or -- in some cases -- when roaming on networks employing 
>similar technology.
>
>COPS provides a generic interface to key HLR functions, translating 
>user data and signaling technologies from cellular protocols to 
>Internet protocols (IP) and vice versa automatically. This allows 
>several protocol-specific gateways to be built, each allowing data 
>stored on the HLR to be accessed by a different type of network. 
>Building an HLR with this software architecture allows for customer 
>databases that can be updated automatically, accessed by multiple 
>network types, and support both voice and high-speed data services.
>
>With COPS, if a mobile operator were to change the type of signaling 
>protocols used on the telecommunications switches of a particular 
>network, the HLR associated with the previous signaling protocol 
>would still be able to communicate with the network. This would 
>allow operators to provide services across multiple network types 
>without interruptions or the addition of multiple HLRs.
>
>``With this technology breakthrough, carriers will be able to more 
>easily migrate from one network protocol to another without 
>replacing the HLR. Additionally, callers will be able to use their 
>phones the same way on a guest network -- including networks in 
>other countries and regions -- that they do at home,'' said Krishan 
>Sabnani, vice president of Bell Labs' Networking Research Laboratory.

>generated more than 28,000 patents since 1925 and has played a
